How Converse sizing works

Here is the answer you came for: yes, Converse Chuck Taylor All Stars run big, by about a half size. Order a half size down from your usual US sneaker size and you will land on the right fit far more often than not. If you wear a 10 in most sneakers, buy a 9.5 Chuck. That one rule solves the question for the vast majority of feet, and the calculator above applies it for you and hands back the UK, EU, and CM equivalents while it is at it.

Why the confusion in the first place? Chucks are unisex. Every pair is built on a single men's last, which is why the tongue label lists two numbers: the men's size and the women's size for the same physical shoe. The women's number is always the men's number plus 1.5, so a men's 8 and a women's 9.5 are literally the same sneaker. If you shop by your women's size, you are still buying a men's-lasted shoe; the label just translates for you.

The formula

Chuck size = your usual US size − 0.5
Women's = Men's + 1.5
UK = US men's − 0.5
EU = US men's + 33
CM = (US men's + 22) ÷ 3 × 2.54

Your usual US size is what you wear in most everyday sneakers, in the same system (men's or women's) you selected above. UK, EU, and CM are computed from the men's number, so a women's size is converted to its men's equivalent (women's minus 1.5) first. CM is the foot length the size is built for, rounded to one decimal.

Every row is one physical shoe shown five ways. Remember these are the sizes printed on the Chucks themselves; to pick your row, take your usual sneaker size, subtract a half size, and find that number in the men's or women's column.

Worked example

You wear a US men's 10.5 in most sneakers. Half size down gives a men's 10 Chuck. That same shoe is a women's 11.5, a UK 9.5, an EU 43, and is built for a foot length of (10 + 22) ÷ 3 × 2.54 = 27.1 cm. Order the men's 10 and the tongue will read 10 on the men's line and 11.5 on the women's line.

When NOT to size down

The half size down rule assumes an average width foot and normal socks, and it is worth breaking in a few situations. If you have wide feet, stay at your usual size: Chucks are not a wide shoe, and the extra length is what buys your forefoot some room. Same call if you plan to wear them with thick socks, in cold weather, or over orthotic insoles. And keep the style in mind: this page's rule is for the classic Chuck Taylor All Star. Chuck 70s run closer to true size thanks to a slightly snugger, more structured fit, and One Stars and other styles vary enough that we will not pretend one rule covers them. When in doubt between two sizes in a canvas shoe, slightly roomy beats slightly tight, because canvas barely stretches lengthwise.

Frequently asked questions

Do Converse run big or small?

Converse run big, by about a half size. The Chuck Taylor All Star is built on a generous last, so ordering a half size down from your usual US sneaker size gives most people the right fit. If you are between sizes or have wide feet, staying at your usual size is the safer call.

Should I size down in Converse?

Yes, a half size down from your usual sneaker size is the standard advice for Chuck Taylor All Stars and it works for most feet. Skip the size down if you have wide feet, plan to wear thick socks, or you are already at the small end of a half size range. A full size down is almost always too far.

Why does the Converse tongue show two sizes?

Because Chucks are unisex and built on a single men's last, the tongue lists both the men's and women's size for the same shoe. The women's number is simply the men's number plus 1.5. A men's 8 and a women's 9.5 are the identical physical shoe, not two different fits.

Do Chuck 70s fit the same as regular Chuck Taylors?

Not quite. The Chuck 70 has a slightly narrower, more structured fit and runs closer to true size than the classic All Star, so many people take only a half size down or none at all. If you already own All Stars, expect the 70 to feel a touch snugger in the same size.

What is my Converse size in EU or UK?

For Converse, the UK size is the US men's size minus 0.5 and the EU size is the US men's size plus 33. So a US men's 10 Chuck is a UK 9.5 and an EU 43. If you know your women's US size, subtract 1.5 to get the men's number first, then convert.

Do all Converse styles fit the same?

No. The classic Chuck Taylor All Star runs about a half size large, the Chuck 70 fits closer to true size, and the One Star and other styles vary from pair to pair. Use the half size down rule as your starting point for All Stars and check style-specific guidance before ordering anything else.
